The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a long stretch ahead at Jaconé, and it’s a real mixed bag – some proper standouts, but plenty of flat or blown-out days too.
The next few days are pretty ordinary. Monday morning you’ll find small 4ft east swell but it’s only 6 seconds, weak energy (174), and while the wind is light offshore, conditions are just “surfable.” Nothing to get excited about. Monday afternoon turns cross-offshore and drops to 3ft. Tuesday morning is even smaller at 2ft, but clean with a light offshore again. It’s a slow start.
Then Wednesday 5th August morning brings a jump. A clean 3ft south swell with a much better 12-second period, and the combined energy hits 617 – moderate, but feeling way more solid. Winds are light offshore. This is genuine surfable quality, and the best of the first week. The south direction is right in the sweet spot for the break. The afternoon is more marginal.
Thursday 6th and Friday 7th mornings see waist-to-chest high waves, 5ft to 5ft from the ENE, with 7-8 second periods and a moderate energy reading (309-366). Offshore or cross-offshore winds keep them clean. Friday afternoon actually goes glassy with 3ft – clean and pretty, but small.
Now hold on, because Sunday 9th August is a standout. Morning brings 6ft from the SSW, a 15-second groundswell, and the energy jumps to 1438 – strong. Winds are light cross-offshore and conditions are clean. This is “excellent” for experienced surfers. The afternoon stays clean with offshore winds, 6ft, and 13-second period, energy at 1630. This is the best session of the whole forecast. The only catch: that long period groundswell tends to jack quickly on beach breaks, so it might be more suited to the points or reefs if there are any around. It’s a serious swell, over 5ft, so beginners should sit this one out.
From Monday 10th to Wednesday 12th, it goes ugly. Onshore winds, rain, and messy conditions. Swell gets big – up to 8ft on Wednesday 12th – but with strong onshores and a cross-on flow, it’s a complete mess. The energy is through the roof (2458 on the 11th), but it’s not for paddle surfing. Honestly, this looks more like a kite-surfing setup than a surfing one.
Thursday 13th August morning cleans up dramatically. Glassy conditions, 5ft from the SSW, 10-second period, and energy at 559. Winds are dead calm. This is a very good morning, especially for intermediate surfers. The afternoon is clean too with cross-offshore breeze.
But the real monster arrives Friday 14th August. Morning: 8ft from the south, 16-second period – that’s very long-period groundswell. Energy hits 3435. Winds are light offshore. This is “excellent” for experienced surfers only. That’s over 8ft, so it’s expert territory. The afternoon stays 8ft but gets a strong cross-offshore wind, making it more marginal.
Saturday 15th August morning is still pumping: 7ft south swell, 13-second period, light offshore, energy 1416. Another excellent session for experienced surfers. The afternoon is a step down due to stronger wind.
The wave energy slowly fades from there. Sunday 16th is a clean 4ft with offshore wind, but only moderate energy. Monday 17th is glassy and small at 3ft. The last real highlight is Tuesday 18th August morning: 6ft from the east, 8-second period, glassy conditions, and 644 energy – very good for a clean, punchy beach break.
The real standout here is Sunday 9th August – that’s the one to circle. The Friday 14th and Saturday 15th are huge and clean but only for the brave. The water temperature is 73°, which is pretty normal for this time of year – no surprises there.
The break is consistent, and crowds are “sometimes,” so expect some company on the good days but not a circus.
Signing off,
Rusty

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
